Anchor handling tug/supply vessel

Smit Kamara

During the last quarter of 2003, Vuyk was contracted by Smit Engineering - part of the SMIT Group now part of Royal Boskalis- to review a basic design for a dynamically positioned anchor handling tug/supply vessel (AHTS), providing a basis for modular upgrading to diving support, oil recovery and other duties. In the first phase, SMIT intended to order two 70-ton bollard pull vessels and one 120-ton bollard pull AHTS. After an international tender, resulting in offers from yards in The Netherlands, Norway, Spain and Singapore, Smit Transport & Heavy Lift B.V. ordered in March 2004, two 70-ton bp AHTS from the Keppel Singmarine yard in Singapore with an option for two 120-ton bp AHTS. In July 2004 Smit exercised its option to build this vessel.

Classification 

All vessels are certfied by American Bureau of Shipping for the class notation:
A1(e), Offshore Support Vessel, Anchor Handling Towing Vessel, AMS,
ACCU, FiFi Class 1, +DPS-2

The first AHTS - named 'Smit Kamara' - has been contracted by the Nederlandse
Aardolie Maatschappij B.V.'(NAM) for a 5-year charter period.
The second 70-ton bollard pull AHTS - named 'Smit Komodo' - shall also be fitted
as Diving Support Vessel. For this purpose this vessel shall have two 850 kW bow
thrusters and two 550 kW stern thrusters, enhancing dynamic positioning
capabilities. Furthermore the vessel can accommodate 50 persons instead of 42
persons.
The 'Smit Komodo'' will be deployed on a long -term charter in Egypt and the 120
ton bollard pull 'Smit Nicobar', which is due for delivery June 2006 and will start a
charter in Sakhalin, Russia.

On March 31, 2006 SMIT announced that they have reached an agreement for the
purchase of seven newly built work vessels from Hadi H. Al-Hammam Est. of
Saudi Arabia. These vessels of approximately 75 tons bp are a modified version of
the 'Smit Kamara' and 'Smit Komodo'' The first two vessels of this new series will
be delivered during 2006 and the last one is expected to be delivered in 2008.
They will be managed by the SMIT Singapore organisation.

Vuyk scope of work

Vuyk Engineering Rotterdam assisted Smit Engineering to compare the various
shipyards offers in technical and commercial way and made ship motion
calculations to advise for the correct configuration of main propulsion, bow and
stern thruster to obtain the DP-2 class notation.
