Offshore Platform

The offshore port is a fixed structure; like a rig with loading-unloading terminal facilities for either bulk (fuel, petrochemical) or containers and relevant.

The offshore terminal consists of a mooring and fluid transfer system, connected by means of either subsea or oversea pipeline to the storage facility onshor

BANGLAMARK is an engineering company structured to manage and develop complex projects, starting from feasibility study, basic and detailed design up to site supervision of installation work. The design is carried out in accordance to the relevant of Oil &Gas international standards including API, BS, EN, ISGOTT, OCIMF, PIANC. SIGTTO and the guidelines of the leading Oil Companies. The Company internal resources cover civil, mechanical, electrical and instrumental design for the development of new marine terminals or the revamping of the existing ones.

Our Concern in Offshore Terminal

Single Buoy Mooring (SBM)

A Single buoy mooring (SBM) (also known as single-point mooring or SPM) is a loading buoy anchored offshore, that serves as a mooring point and interconnect for tankers loading or offloading gas or liquid products. SPMs are the link between geostatic subsea manifold connections and weather vanning tankers. They are capable of handling any tonnage ship, even very large crude carriers (VLCC) where no alternative facility is available.

Conventional Buoy Mooring (CBM)

The Conventional Buoy Mooring (CBM) system includes multiple buoys that are fixed to the seabed by means of mooring lines and marine anchors. The three to six buoys are permanently installed in a rectangular pattern that allows safe mooring of a vessel which is positioned between the buoys with tug assistance.

The buoys provide the strong points to which the vessel’s on-board mooring lines can be attached. It can also be combined with a fluid transfer system that enables connection of (subsea) pipelines to the midship manifold of a conventional tanker. When no tanker is moored, the submersible hose or hoses are stored on the seabed. For cryogenic fluids, the aerial hose is suspended from a tower to the midship manifold of the liquefied gas carrier. The system can be designed to berth all sizes of tankers but, in general, tanker size typically ranges from 5,000 to 60,000 DWT.

Fixed Jetty System

A fixed platform is a type of offshore platform used for the unloading of LPG. These platforms are built on concrete or steel legs anchored directly onto the seabed, supporting a deck with space for drilling rigs, production facilities and crew quarters.

Such platforms are, by virtue of their immobility, designed for very long-term use. Various types of structure are used, steel jacket, concrete caisso, floating steel and even floating concrete.

Offshore Floating Jetty

Floating jetty is a platform or ramp supported by pontoons. It is usually joined to the shore with a gangway. The pier is usually held in place by vertical poles referred to as pilings, which are embedded in the seafloor or by anchored cables.

Marine Dredger

Dredging is a displacement of soil, carried out under water. It serves several different purposes. One of the applications meets the need to maintain minimum depths in canals and harbors by removing mud, sludge, gravel and rocks. Maintenance dredging is now only a basic task, while other fields are growing in demand much faster: creating new land for port and industrial development; trenching, backfilling and protection work for offshore pipelines, coastal outfall pipelines and for cables laid on the sea bed; environmental dredging and clean-up of contaminated sediments; replenishment of beaches and coastlines, not only for coastal protection, but also for recreational uses.

We, BANGLAMARK knows designing and building the exact custom dredging solution that will boost your efficiency and lower your costs involves working with you. Starting with the base model, we customize your workboat for your specific application, learning all details of your project, and involving you every step of the way. We have vast experience, for the design and supply of efficient and integrated dredgers and dredging equipment.

Mechanical Dredger

Mechanical excavating is applied to cohesive soils. The dredged material is excavated and removed using mechanical means such as grabs, buckets, cutter heads or scoops.

Backhoe Dredger
Backhoe dredgers (BHDs) are stationary dredgers with a hydraulic excavator installed on a pontoon. The backhoe dredgers can dredge a wide range of materials very precisely and they operate mainly in shallow and enclosed waters.

Bucket Chain Dredger
The bucket dredger is one of the mechanical dredgers. A bucket dredger is a stationary dredger that is equipped with a continuous chain of buckets, which are carried through a structure, the ladder. This ladder is mounted in a U-shaped pontoon. The drive of the bucket chain is on the upper side. The bucket dredger is anchored on six anchors. During dredging, the dredger swings round the bow anchor by taking in or paying out the winches on board.

Cutter Suction Dredger
A Cutter Suction Dredger (CSD) is equipped with a rotating cutter head, for cutting and fragmenting harder soils and rock. The material is sucked up by means of dredge pumps, and discharged through a floating pipeline and pipes on shore, to a deposit area.

Grab Dredger
A grab dredger picks up seabed material with a clam shell bucket, which hangs from an onboard crane or a crane barge, or is carried by a hydraulic arm, or is mounted like on a dragline. This technique is often used in excavation of bay mud. Most of these dredges are crane barges with spuds, steel piles that can be lowered and raised to position the dredge.

Hydraulic Dredger

Hydraulic excavating is done with special water jests in cohesionless soils such as silt, sand and gravel. The dredged material which has been loosened from the sea-bed is sucked up and transported further as a mixture (solid material and water) using centrifugal pumps.

Plain Suction Dredger
The characteristic of a plain suction dredger is that it is a stationary dredger, consisting of a pontoon anchored by one or more wires and with at least one sand pump, that is connected to a suction pipe. The suction tube is positioned in a well in the bows of the pontoon to which it is hinged.

Trailing Suction Dredger
A trailing suction hopper dredger is a ship that has a full sailing capacity used to maintain navigable waterways, deepening the maritime canals that are threatened to become silted, to construct new land elsewhere or to replace sand eroded by storms or wave action on the beaches.
