Our Products and Services
We provide, with our fleet of trailing suction hopper dredgers; a grab dredger; a bed levelling tug and various hydrographic survey craft, a comprehensive Dredging and Hydrographic Survey solution, as detailed in our list of product and services below.
Hydrographic Surveys
A team of trained hydrographers perform hydrographic surveys of ports and dams using specialised equipment, comprising positioning systems, echo sounders and computers with software for data collection and processing.
A Comprehensive Depth Management Service
Depth Management involves the provision of a holistic lump sum price type service. The customer states his depth requirement, and for a fixed price, Dredging Services ensures these.
The advantage to the customer is that he would not need to be involved with the details of the dredging activities, or be exposed to the varying costs of executing each of these activities.
Consultancy Services Including Training
Consultancy services in all aspects of dredging and hydrographic surveys as well as dredging techniques are available.
Training on the use and maintenance of dredging and hydrographic equipment is also provided.

Dam Surveys and Dredging
It is responsible for the safe, effective and efficient economic functioning of the national port system. TNPA’s role includes managing the port system in a landlord capacity and providing port infrastructure and marine services to the eight ports in Richards Bay, Durban, East London, Ngqura, Port Elizabeth, Mossel Bay, Cape Town and Saldanha. Marine services provided include dredging, aids to navigation, ship repairs and marine operations.
TNPA's vision is "A system of ports, seamlessly integrated in the logistics network that is jointly and individually self-sustainable through delivery of high levels of service and increasing efficiency for a growing customer base, enhancing South Africa’s global competitiveness and facilitating the expansion of the South African economy through socially and environmentally sustainable port development"
The Ilembe contract includes construction of a combination workboat / hydrographic survey boat (Inyosi). This will be used to take stores, spares and crew to the Ilembe and will accompany the Ilembe to other ports. It will enable the Ilembe to be self-sufficient, saving on fuel as it won’t have to move around the port and will not require tugs to transport crew and spares.
The workboat can be lifted onto the Ilembe using its crane. Royal IHC has sub-contracted the manufacture of the Inyosi to a Cape Town based company – Nautic Africa - as part of the supplier development aspect of its contract in order to create jobs, pass on expertise and develop skills. All contracts for new equipment include a supplier development component comprising 25 percent of the value of the contract, for local manufacture of parts, as well as skills transfer.
All hydrographers use PDS 2000 and Hypack software for obtaining, processing and plotting of data.
Survey launches include:
The Sonar: fiberglass ski-boat, 100 hp.
Swift: fibreglass ski-boat with two 40kW outboard motors.
Stretford end: semi rigid ski-boat, 100 hp.
Wizard: an 8m semi-rigid inflatable ski-boat powered by two 100 HP outboard motors, designed to perform single and multi- beam surveys.
Fortunati: a 6.92m catamaran ski-boat powered by two 110 HP outboard motors for single beam soundings.
