New Builds

DORMAC (New) Build is a Strategic Business Unit created to exploit the demand from international ship and local owners for niche or tonnage vessels, specifically, double hulled bunker barges, harbour, pusher tugs and dumb barges.

This opportunity is the result of an increase in ship building activity internationally, which is exceeding available capacity. Subsequently the majority of ship building yards are turning away orders for building smaller vessels allowing greater focus on larger capacity vessels.

DORMAC (New) Build, as a consequence of its historical new building experience and infrastructure, can construct complete vessels or modify/convert existing vessels to a client's specification and design or from specification only, utilising external design capability.

Construction projects are currently managed by a dedicated new building team comprising engineers, planners, estimators, quality controllers, all utilising internal fabrication skills and a very adequate yard infrastructure.

DORMAC has invested heavily in infrastructure for new builds including upgrading gantry cranes and grillage areas with the latest state of the art welding equipment.

DORMAC: CAPE TOWN & SALDANHA BAY

DORMAC Cape Town and DORMACSaldanha Bay are strategically positioned close to the entrances of these main Ports.

The entire spectrum of repairs including cofferdam projects, are part of the daily services 24 hours a day, 365 days a year.

The West Coast of Africa is a major hub for oil exploration. DORMAC Cape Town and DORMACSaldanha Bay have over the last 2 years, been involved with numerous repairs to drill rigs, semi submersible mobile offshore drilling units, offshore supply vessels, research vessels, anchor handling tugs, general cargo vessels, container ships, tankers, passenger liners and harbour tugs.

The proximity of Cape Town and Saldanha Bay to both the East and West Coast oil fields has resulted in these ports becoming a haven for repairs which are safely completed in these two Ports.

Repairs to Container vessels, Cargo ships, passenger liners, offshore mining vessels and Navy ships have been an every day service, who again and again returns to utilize DORMAC Cape Town and DORMACSaldanha Bay.

The covered fabrication shops with 10 & 5 ton overhead cranes and our "take out" yards allows DORMAC Cape Town and DORMACSaldanha Bay to facilitate the reconditioning of main engine and auxiliary engine parts, jig & assembly of heavy duty schedule piping, cofferdams, overhauling of sea water valves, hydraulic cylinders and rams as well as steel fabrication.

DORMAC : RICHARDS BAY

Richards Bay is situated 160 km northeast of Durban. The Port of Richards Bay currently occupies 2,157 ha of land area, 1,495 ha of water area and has the potential to expand whenever required. The Port currently has 21 operational berths in service.

The Port currently has no ship repair facilities, however a large facility is being planned and a dry or floating dock is under consideration. Ship repair is undertaken on the quayside and has to be coordinated and planned with vessels staying berthed alongside.

This been said, Dormac Richards Bay, strives to supply a full and efficient service in the Industrial and Marine fields. The backbone of this branch is the unified spirit of its staff and management, whose highly competitive and motivated nature allows them to provide a highly efficient and professional service in both fields. As mentioned earlier, ship repairs are coordinated and planned around a vessel's stay in Port, however, there are occasions when emergency repairs are required. The Port will allocate an available berth to carry out these repairs. Although, the port lacks a dedicated repair quay, dry or floating Dock, Dormac is still able to offer the following marine services:

  • fitting
  • electrical & mechanical works
  • steel works
  • fabrication
  • AC & reefer plant repairs
  • Spare parts
  • Cofferdam repairs
  • Underwater services
  • Main engine repairs
  • Engine room & tank cleaning

SUCCESSFUL PROJECTS CARRIED:

  • bulkhead renewals
  • hatch cover repairs
  • cranes' repairs
  • fabrication & installation of access ladders & platforms
  • overhauling & rewinding of motors

As the Port of Richards Bay expands and develops further over the next few years, potentially developing into one of the world's busiest bulk loading ports, at Dormac Richards Bay are looking to expand their services to match its growth and expansion.
