Esvagt Carpathia is the first of six sistervessels from ASL Shipyard in Singapore.
Esvagt Carpathia: Ready to spend
two years on duty
Esvagt A/S is looking north on the ocean, after signing five contracts with Norwegian Statoil for five ships over a period of two to five years.
“A milestone in Esvagt’s history”, says Ovin Carlsson, CEO of Esvagt. “We have been working on the Norwegian market for a long time, which seems to be fruitful now and in the future.”

One of the contracts concerns a ship for delivery in 2009, going directly to the Statoil contract for five years. So it will not be available before 2014.
The three other ships are all newbuildings of the C-class vessel from ASL Shipyard in Singapore. The two other contracts are for the two Ulstein X-bow units under construction in Bilbao, Spain. The last two C-class newbuildings from Singapore are still not fixed for any assignment, but are kept open in order to operate in the future market.
The first
The first in the series of six units ordered by Esvagt was delivered in March and named the Esvagt Carpathia in her homeport of Esbjerg on April 18, 2007, before taking off for a Norwegian contract with AGR Petroleum for standby duties on the Norwegian field called DNO 24/7-2, west of the Ringthorne field, which in turn lies due west of Haugesund on the Norwegian mainland.

The foredeck of the Esvagt Carpathia can be used for helicopter evacuation. |
The Esvagt Carpathia is on this field as a rescue boat in case anything goes wrong on the drilling operation on the field, day after day in a 24/7 operation. The ship stays on field until further notice as the crew change and bunkering operation take place while at sea.
The crew change takes place every fortnight – part of the crew is changed by their own “bus” to Esbjerg. Esvagt’s crew change and multi-task vessel the Esvagt Alpha sails from Esbjerg with crew onboard. When it arrives on the Norwegian field the change takes place with the use of the fast rescue boat. A well-known manoeuvre for Esvagt’s crew, as the system is the same on the
Danish sector in the North Sea.
The standby vessel only comes to port every second year unless technical failure forces the ship to shore.

Singapore built
ASL Shipyard in Singapore built the Esvagt Carpathia as hull no 807. The shipyard, with quite good contact with the Danish A.P. Møller-Mærsk Group as the owner of Esvagt, Svitzer A/S, has a
substantial order portfolio at the yard. The Esvagt Carpathia was designed by Esvagt in co-operation with Ole Steen Knudsen, Aarhus, and is developed on the Spanish built sister vessels the Esvagt Capella and the Esvagt Corona from Zamakona in
Bilbao. A number of adjustments have been made while building in Singapore.
Tall hull
The ship is 46.1 metres overall and has a very tall hull in the bow section to avoid water on deck. On top of the foredeck is a platform for operations with helicopters. Not a landing pad, but a platform for winching people on and off the vessel. Under the helicopter platform is a closed room for the anchor winches and storage in general.
The vessel is authorised for the rescue of 300 persons in the British sector, while in the Norwegian, Danish and Dutch sectors it is authorised for 120 persons onboard at the same time. Several special compartments have been made in the ship to accommodate rescued persons. The variation in the number of rescued persons depends on the circumstances in each country. On the platforms – fixed, jack-ups or semi-subs – the three countries always have a crew of not more than 110 persons, so the capacity of 120 is sufficient.
In the British sector there can be more
persons on each platform, and thereforeso the capacity is higher for a short period if an accident occurs. The ship is fitted with arrangements for towing, if this is needed to secure the platform. She is also equipment to use if a dead ship is on a dangerous course towards the platform.
Futhermore the Esvagt ship is fitted with equipment to take care of an oil spill. Apart from this task, Esvagt ships in general are used for a number of other jobs while on duty at sea. In the Danish sector they have been used as “trucks” for goods between platforms on the same field.

Truck and hotel
If a piece of equipment is too big to be carried by manpower from one platform to another, it has to go down on a ship and is transferred by sea to the next platform – often on an Esvagt ship.
The standby rescue vessel can also be used as a floating hotel in the vicinity of a platform. If a certain repair job requires too many people and the number is above the limit on the platform, they can be accommodated on the standby ship. They are lowered from the platform in a personnel basket in the evening and taken back in the morning at start of work.

Diesel electric ower
A diesel electric plant will power the Singapore built Esvagt sisters, which is more economical than a traditional plant. By using a diesel-electric plant a number of engines can be switched off when the ship is on standby duty and switched on when more power is necessary.
On the Esvagt Carpathia there is a plant with five Cummins engines type
KTA-19-D, each developing 485 kW to a total of 2,425 kW. They supply the power to two electric motors, each of 715 kW, driving two azimuth propellers. This gives a services speed of 12 knots.
