Palma Shore Services (PSS) will provide first class turnkey solutions for receiving, handling, discharging and landing bulk, breakbulk (including OOG and heavy lift) and containerised cargoes ashore in the remote region of Palma, in the Cabo Delgado Province, Republic of Mozambique.
PSS will establish Temporary Cargo Offloading Facilities (TCOF) in the Afungi bay area in locations, which have already been secured and extensively surveyed both above and below the high water mark for suitability for the proposed operations.
Each TCOF will consist of a beachhead landing site, a laydown area for cargoes, all cargo handling equipment as required, as well as base and fly camps to house all PSS and Comarco support personnel to sustain 24 hour operations.
Each TCOF will be well supported both offshore by marine equipment supplied by Comarco and designed to handle the specific requirements of cargo transport and beaching, and onshore for the delivery of cargoes from laydown to receivers warehouse within a fifteen km radius.
Comarco has an extensive and well documented background in such operations and, by virtue of its experience in both the region and in the marine contracting industry in general, Comarco, together with PSS, is well aligned to provide a bespoke solution for almost any cargo requirement in this remote region.
PSS is of the opinion that this method will represent the quickest, safest and most cost effective means of delivering the intended high volumes of cargo ashore directly into the Palma region.
Afungi Bay has a good deep water approach and a sheltered anchorage, which lends itself well to the proposed offshore and transshipment at sea operation.
This will enable Comarco to deliver the cargo ashore by barge either directly from nearby port of loading, or having received the cargo directly onto the barge(s) from ocean going vessels at the RVP anchorage.
The principal challenge, however, lies in the fact that there is a 600 – 800m intertidal zone, which is exposed at low water and practically flat, with a 1 in 200 slope from beach head to drop off. In order to overcome this, Comarco will install beachheads at each beaching location adjacent to each TCOF.
Comarco has developed a Rapidly Deployable Beachhead or RDB solution for creating environmentally friendly, temporary landing facilities in remote locations. So named because the RDB may be quickly constructed and removed,
By nature of its construction, the RDB may be built with supervised unskilled manual labour and minimal equipment at remote locations in a very much shorter time span than conventional piled jetties and at a far more cost effective rate.
The bulk of the materials used to construct the RDB are available immediately locally and are supplemented with geotextile material for cohesion and structural integrity.
Unlike a conventional jetty, the RDB may be removed very quickly after use and is environmentally friendly, leaving no evidence of its prior existence within a matter of days of removal.
The RDB structures proposed for Afungi will be 200 metres long and 30 metres wide. Each RDB will be 3.00 metres high at the seaward end of the RDB and will be suitable for the berthing of vessels of up to 2m laden draft.
Comarco has used RDB’s throughout the East African seaboard for many years, starting with a 500m long sandbag construction for Amoco in Madagascar in 1985 and using this system several times in Mozambique.
Due to the difficulties of operating in such exposed beaching locations, Comarco has developed the beach landing system known as the Exposed Beach Operating System or EBOS. It is a system of deploying breasting lines running along taught winch lines either side of a barge with a 3rd winch to pull the loaded barge into position onto the beach. This system is especially effective when working on exposed beaches with adverse wave, wind and current action.
Whilst relatively sheltered, the area of Afungi bay does have cross currents and regular strong winds, particularly in the afternoons, and wind speeds of 20 - 35KTS are not uncommon. Such wind against the hull and side walls of a 230ft barge would act as a sail, (particularly given the low draft and high side walls above the waterline) and for safety reasons for beaching operations over an extended time period and at night, this operation would require tight control. Comarco will utilise a lighter system, known as the SBOS (Safe Beach Operating System), to regulate and control the beach landing operations in Palma. The SBOS provides breasting lines to be attached to the bollards on the barge and form a direct line ashore to guide the barge into position at right angles to the beach.
This system has already been tried and tested in Mozambique by Comarco during the MOMA Sands Phase II and has proven to be quick to install, safe to operate and has no negative environmental impact.
All beach landing operations will be carried out by Comarco, using experienced Beaching Superintendents, and will be supported ashore by a Comarco Marine Superintendent.
Considerations such as weather, barge draft and tide will all play a significant impact on beaching the barges.
Weather: A site specific weather report shall be provided by a specialist meteorological service twice daily for the duration of operations in Afungi bay and will be reviewed prior to any beaching operations to ensure conditions are favourable.
Barge Draft: The draft of the barge will be a major factor in the beaching operation and will always be considered prior to operations.
Tide: The mean tidal range in Afungi bay is approximately 3.0m. The beaching of the barges in Afunghi will always take plase at high water.
Given the gradual gradient of the immediate approaches to the RDB the assessment of the tide will play a significant role on when to beach the barge.
The Marine Superintendent together with the Beaching Superintendent will have the final say of when the beaching will take place.
The Comarco barge(s) will be beached against the RDB at high water and secured in place using the SBOS.
As the tide ebbs, the barge will sit on the beach and provide a firm stable platform from which to discharge.
The cargo will be discharged from the barges using cranes, forklifts and wheel loaders, depending on the cargo requirement, and loaded to trucks for shunting to the laydown area at the TCOF.
At the TCOF, the cargo will be tallied and inspected. Upon verification and release by the Mozambican authorities, the cargo will be delivered to the receivers yard or warehouse within a 15km radius of the TCOF.
Comarco will provide all personnel required for all aspects of the offshore, beach and foreshore operations, including specialist personnel such as HSE Superintendents, Beaching Superintendents, Marine Superintendents, Offshore Superintendents, Onshore Superintendents, Barge Supervisors, Rigger Supervisors, Truck Pushers, Operators and Riggers. All personnel are trained, certified and well experienced in these operations and in Mozambique.Comarco will continue to employ Mozambican nationals in all such positions, based on experience, qualifications and training. Comarco will continue to implement and conduct regular training sessions in country to develop and certify local personnel.
Comarco was established in 1971, in Mombasa, Kenya before expanding its range of activities and area of operations throughout the entire Indian Ocean and along the Eastern Africa Seaboard. Comarco is now the leading marine and specialised logistics contractor in the region with over forty years of experience.More about Comarco
