More about Anchor Handling Tug Supply Vessels (just for  general knowledge and educational info):
Offshore Anchor Handling is an activity that can be termed as thrilling as well as dreary, tiring, petrifying and more often than not professionally very rewarding. Anchor handling as a whole is able to test the vessel handling proficiency of expert handlers and even the master’s patience to the limits. To better understand and imply such intense vessel handling techniques, one has to devote a lot of time at sea and be constantly focused.
Anchor Handlers or Anchor Handling Tug Supply Vessels are very powerful ships that deploy, recover, and shift a sub-sea mooring pattern. These vessels are normally seen working with offshore installations. Either one or a fleet of anchor handlers (AHTS) co-operate with each other and work as a unit. During the demanding operation of Anchor Handling of an offshore installation such as a Drilling unit or even a Semi-Submersible Rig, these offshore vessels are assumed to be ‘slaves’ when assisting the vessels whose anchors are to be worked upon.
Prudent professionalism and total co-operation is required by  personnel  while performing such complex jobs. During anchor handling operations, heavy machinery and related equipment are repeatedly pushed to their extreme in a very hostile environment. Breakdowns do happen, although not frequently, but when they are most unexpected. Such tough working conditions are ripe for causing serious damages to the vessel and her crew as a result of inadvertent  brushing  with the installations while working in close proximity, vessel’s motions due to the sea conditions and when  maneuvering  with high tension wires, chains, etc.
Anchor Handling Tug Supply Vessels are super strengthened, purpose built and different from the  harbor  tugs, or even the ocean going ones. The newer anchor handling tugs are built to survive the toughest conditions of the sea, keeping in mind safety, comfort and complete efficiency of the crew. They have limitations and applications of their own, making them the superior choice for sub-sea mooring operations in the offshore Oil and Gas fields.
All such Anchor Handling Tug Supply Vessels  have certain things in common and have a range of work process in specific areas. The job requirements go along with the characteristics which are as mentioned below –
- AHTS vessels have superior bollard pull and a higher engine rating (BHP) which makes them powerful enough to be  utilized  for  specialized  jobs such as Anchor Handling.
- They are fitted with a combination of multiple thrusters (Bow and Stern)with twin-screw CPP systems  providing tremendous vessel handling features that allows such vessels to work in any sea condition.
- Large amount of strengthened deck space astern of the accommodation areas allow even the largest of the anchors, heavy wires, chains, buoys and other related equipment to be stowed and handled.
- AHTS have an extremely powerful multi-drum system catering twin winches, one each for towing and anchor handling purposes. This is apart from the combination of other spare drums and work winches used especially for towing and deep water anchor handling.
- Sufficient amount of anchor chain can be stowed on board these vessels due to the availability of larger capacity chain lockers.
- AHTS are multipurpose vessels that can even perform the duties of the ordinary supply boats such as carrying large quantity of water, fuel and deck cargo.
Similarly, the Anchor Handling Tug Supply Vessel (AHTS) can be used up in diverse applications that are  utilized  in the offshore industry. They can be as follows –
- AHTS are used as multipurpose work boats in the oil and gas offshore field. They can perform towing operations, rig moves, execute general supply duties by carrying dry and liquid cargo such as cement, mud, fresh water, fuel oil, etc for the offshore installations as need be.
- If the ocean going tugs are not readily available, then these workhorses can take up to the role of salvaging and rescue.
- Anchor work for rigs, barges, semi-submersibles, construction barges, etc can be executed with the help of these kinds of vessels. These vessels can perform efficiently in toughest sea conditions and also in ultra deep waters.
- Installation of buoys, SBM mooring, sub-sea moorings are ideally done with the assistance of the Anchor Handling Tugs.
- Nowadays, they are progressively being  utilized  for towing and anchor handling of newer offshore structures such as the Tension Leg Platforms (TLP’s) or even the gravity based platforms and likewise.
On the contrary, AHTS vessels are only designed to perform certain tasks that are practically impossible for the other specifically designed offshore work boats such as the dedicated Platform Support vessels (PSVs), Multipurpose Platform support vessels (MPSVs) and likewise. Restrictions of these vessels are based upon the type of work to be carried out such as -
- Most of these vessels have a shallow draft and a design limitation of a wavy stern which is where they lose the pulling power during deep sea operations and are subsequently at their worst during rough sea weather conditions.
- They can be restricted to handle large construction or cargo barges when operating in confined spaces.
- Since they are more often than not confused with the harbour tugs, these vessels are not designed to push other vessels either alongside or at sea.
- These vessels have a limited pulling power for which the towing gears steel deck fittings, tow points and other suitable towing assemblies have to be strong enough in order to perform effortlessly.
Since such jobs are difficult and could endanger lives, taking short cuts, working impatiently, building up frustration and reacting complacently have to be isolated.  The Master and the Crew of such workhorses, hence, have to remain alert at all times and portray swift and positive reactions to avert catastrophic consequences.

ABOUT VARD
Anchor Handling Tug Supply (AHTS) vessels are mainly built to handle anchors for oil rigs, tow them to location, anchor them up and, in a few cases, serve as an Emergency Rescue and Recovery Vessel (ERRV). They are also used to transport supplies to and from offshore drilling rigs.
AHTS vessels differ from Platform supply vessels (PSVs) in being fitted with winches for towing and anchor handling, having an open stern to allow the decking of anchors, and having more power to increase the bollard pull. The machinery is specifically designed for anchor handling operations. They also have arrangements for quick anchor release, which is operable from the bridge or other normally manned location in direct communication with the bridge. The reference load used in the design and testing of the towing winch is twice the static bollard pull.
 
Vard can create very specialized vessels catered to the diverse needs of his customers and clients. Whether from Antartica to the northern seas or southern seas, Vard can create specific vessels catered  to each  sea condition and navigation, as well as meet the required precise function of what is to be done and achieved. Apart from building ships, it can also repair and convert ships to meet the needs of his clients. Occasionally, speciailzed naval vessels or icebreakers are also built by Vard. In my opinion, Vard is a ship building company, but also an oil and gas support company. It is niche in it's field, equivalent to Porsche compared to Toyota or Kia if in the car manufacturing business.
Currently this Italian girl is not feeling well and need enough rest. Let's not disturb her sleep. lol. =)

It seems like a lot of investors still very ignorant of Vard's business and its interface in the marine industry.
Gallant for sure is not into O& G or shipping.

Probably he's upset w this ctr lah.
Agreed that opportunities abounds when problem arise.

Any idea whether a short squeeze can happen to this counter? If the outstanding shorts area very huge given that Vard had been heavily sold down. If not many willing to sell when good news come, then will there be a massive short covering?
