The company has a joint-venture (Marine Subsea & Consafe Ltd) with
Consafe MSV AB and Sonangol. The joint-venture has a service contract
with Sonangol and a purchase agreement with Consafe and Yantai for a
semisubmersible crane vessel, Safe Challenger.
Yantai has informed of their intention to acquire Consafe MSV’s interest
in the joint-venture. Yantai has further agreed to take delivery of the unit,
which is to be renamed African Challenger, for its own account and lease
the unit to Marine Subsea under a 10-year bareboat lease with purchase
option. The contract will be transferred to a new JV with Sonangol, Yantai
and Marine Subsea. The terms of the bareboat agreement reflect the cost
of the unit and the payments made to date.
This means that the new JV no longer requires financing and the organisational
model is simplified. The final agreements are expected to be in place by first half
2010. The rig will be delivered end of first quarter 2012.
The SSCV, African Challenger (former Safe Challenger), can provide support
during offshore construction or modification and maintenance, and can also
serve the Inspection Maintenance Repair (IMR) market. The vessel is DP 2
and has 3 000 t lifting capacity, 600 accommodation capacity, and can
provide large lay-down areas. The vessel can be used for heavy lifts, offshore
mooring and, with minor modifications, for pipe lay. The SSCV, comprises
a deck structure supported by columns and pontoons. This configuration
enables very good motion characteristics – far superior to mono-hull vessels.

The company has secured a 5 year service contract for a state of the art
Drillship. A Letter of Intent with Tsakos Commerce has been signed whereby a
Joint Venture company has been established; TEN Marine Subsea Drilling Ltd.
The JV has completed the technical assessment of the various Drillship alternatives
and has decided on a preferred alternative. Tsakos is responsible for the
financing of the Drillship and is actively pursuing this at the current time.
Exploration and production drilling in deep waters is carried out by either
semi-submersible rigs or Drillships. Drillships are particularly well suited to
the benign and deep waters of West Africa.
