Miko Polar Kit 

A new system has been developed for applying Miko magnetic patches to ships that have been holed by ice in Polar waters. This is expected to be of particular value to vessels of all types that are applying for Polar Code certification as it will physically demonstrate their preparedness for dealing with hull damage that might be caused by ice.

Miko Tank Sealer Kit

The Tanks Sealer Kit is a quick, easy and flexible first barrier against leakages on storage tanks.


Statoil has made a significant investment with Miko Marine AS for the supply of 17 storage tank emergency repair kits which it is distributing around its tank farms and refineries. The kits are seen as a valuable form of insurance against environmental damage and the loss of expensive product that would result from a leak opening in a storage tank.

Miko Pipe Plugs WRV-8000

The range WRV-8000 is an expansion plug intended for sealing pipe openings below the water surface. Its used for planned operations during maintenance, in-water survey or repair, as well as for emergencies and salvage operations. Available from a nominal diameter of 18mm to 600mm.

Miko Sea Chest Cofferdams and Sea Chest Covers.

Beside the Miko Plaster® as closing tool for a sea chest developed Miko Marine also the Sea Chest Cofferdam and the Sea Chest Cover. Both tools can be product to the requirements of the customer. There is also a possibility to produce it ROV ready, making it possible to install it under water using a ROV. These tools can be used on any depth.

Miko Salvage Kit

Used world-wide for salvage operations, the Salvage Kit is a proven concept for the temporary and quick repair of damage from groundings or collisions. The FlexiShape Miko Plaster® which is included in the kit, is designed to overcome uneven steel surfaces, sharp edges and large areas of damage to the hull. The Kevlar-reinforced patches are stapled to the hull using the Miko Fix®.

Stopping Drifting Tankers with Miko ShipArrestor 

What do you do with a drifting tanker?
1: Slow it down
2: Rotate its bow up against the weather
3: Provide a towing point
4: Do it all quickly – from a helicopter

…i.e. arrest it!

An abandoned vessel is one of many challenges to salvors. In many cases an emergency towing connection to a salvage tug is the only string preventing a total loss of ship and cargo, as well as harm to the environment. For centuries the salvors had to board the abandoned vessel to establish the emergency salvage connection, a hazardous task putting lives at risk. A great number of vessels have suffered total loss after being abandoned. The associated cost to the shipping industry and its underwriters are substantial. Fortunately no drifting vessel has so far hit an offshore oil -or gas installation.
A challenge to the salvage industry is to connect a towing line to a drifting vessel. For salvors onboard a disabled vessel, sudden sinking is a lurking nightmare.

A drifting vessel represents a serious threat to life and environment. In addition a disabled vessel will normal drift beam to the seas and the roll motions experienced will make it difficult both to board the vessel and to effectuate a possible repair.

Miko’s Sea-Anchor will rotate the bow of even large cargo vessels up against the weather and reduce their drift rate increasing the chances for a successful salvage operation. The combination of a sea-anchor (with diameter up to 40 meters), the synthetic fibre towing line and the pick-up buoy solution provides the salvor more time and when in place, a fast and secure way to connect and start the tow.

The Sea-Anchor may be used as a “stand alone” product, in combination with Emergency Towing Systems for tankers, or as a part of the ShipArrestor as presented earlier.

The sea anchor is self activated when the anchor is pulled through the water.

The particulars of the Sea–Anchor are adjusted to optimise the effect to:

  1. Increase drag force to reduce drift speed by up to 60 %.
  2. The bow of the vessel will be heading towards the environmental forces from wind, waves and current, hence reducing exposed area and motions of the vessel.
  3. The tow-line – sea-anchor combination attached to a pick-up buoy will allow the salvor to – efficiently and safely, pick up the tow and start towing the casualty into a safe haven.
