Year of Build: it was bought new and was installed in 2006, having started operations in August 2006.
- The CALM buoy is fit to work with the following vessel types: Aframax, Suezmax and VLCC’s
- The CALM buoy weight is 390 tons
MAIN BUOY EQUIPMENT
The equipment identified in the following list are only the main elements, not representing their entirety.
Turn Table (Main Roller Bearing)
The Mooring System(anchored 12 chains)
· 6 groups of 2 anchor legs with links between 107 and 178 mm and 355/435 meters long fitted in circle and linked lo 12 MAG anchor type with a weight of 12 up to 27 tons each.
Hydraulic System for PLEM valves operation with one umbilical from the buoy body until the PLEM valves, attached to the south submarine string hoses.
o Sealine Cathodic Protection System and Buoy Body.
This is a CALM (Catenary Anchor Leg Mooring) type. It is a cylindrical buoy anchored by a system of 12 chains connected to an anchor MAG type, and high capacity moorings, allowing the movement of the buoy within certain limits and with the capacity for its replacement in the theoretical position, with high elasticity and energy absorption capacity.
The buoy body consists of an outer structure and an inner cylindrical structure connected by top and bottom faces forming a welded structure, which is internally divided into bulkheads in 12 watertight compartments, 6 of which are upper and 6 lower separated by a horizontal bulkhead. such that even if two adjacent compartments are flooded, the buoy will survive.
The lower part of the buoy's body is equipped with a skirt that accommodates 6 pipe- chains with glands and jaws, each aligned with a bulkhead or frame. At the top of the float is a machined support structure for the main bearing. The skirt acts as a buoy hull defense. In addition, it reduces roll, stern-bow and Port&Starboard movements.
Two man-made passages allow access to stairs that going down through the central well at deck level to a central platform welded inside the central well, thus allowing access to the valves of the product piping. This platform is provided with a non-slip fiberglass floor and gives access to the HPU unit and telemetry equipment.
The critical components of the monobuoy, such as the main bearing, were built to withstand immersion situations and, therefore, the buoy was designed to withstand significant inclinations due to mooring forces and movements caused by waves.
Each buoy compartment has the following components:
One of the compartments has an enlarged hatch that houses the hydraulic control system for the PLEM valves and telemetry and can be used for equipment storage purposes. The compartment 6 has a recess that allows the batteries to be accommodated. The inner central compartment is formed by curved bulkheads that limit the radial compartments and the floor and roof is made of deck plate. This compartment provides additional buoyancy and incorporates the following equipment:
This central chamber also accommodates 2 sections of 16" pipelines for product passage with two 16 " ball valves, manually operated. These pipelines connect the underwater hoses to the central part of the swivel.
Mooring Points - On the deck around the monobuoy and aligned with the structural bulkheads there are 6 bollards for mooring speedboats and support boats. The bollards have a SWT of 15T.
Fixation / Rotation Points - At the top of the float there are 6 eyes that can be used to rotate the plate or to keep it in a certain position. Another 6 eyes are welded to the turntable. Notebooks are used to move the plate to the required position.
Fender - The buoy is protected by a 10"tubular steel fender across the perimeter of the skirt, 48 half-rod bars approximately 76 mm in diameter around the buoy body and an 8i? diameter steel tube placed the entire perimeter of the top of the buoy.
The scope of removing the CALM buoy is on seller scope and will take place between May and August this year.
