    • Underwater services and diving support, including the provision of air diving spreads and ROV services
    • Managing hose change outs and replacement/installation of SPM configurations

  • Maintenance dredging

    Maintenance dredging

    It is of prime importance for terminal operators to safeguard navigability of the access channels to their terminals, the turning basins, the immediate access to their berthing areas and the berthing spaces.

    Depending on the location of the terminal and the degree of sedimentation calculated, this requires the routine removal of accumulated sediment at regular intervals to maintain the navigation and berthing areas at their design depths.

    CTOW can rely on the extensive experience and the pooling resources of their shareholders, who have a wealth of experience in large-scale maintenance dredging in navigation channels, but equally in accurate and economically viable maintenance dredging amongst others with Water Injection Dredging (WID) or smaller flexible dredging equipment in limited areas and along berths.


  • Hydrographic surveys

    Hydrographic surveys

    Hydrographical survey is essential for most marine tasks, not least for the safe and secure operations of access channels to port and terminal locations.

    CTOW has access to in-house expertise and survey equipement. Secure mapping of access channels and offshore structure such as pipeline connections to SPM’s are of paramount importance. We have developed the necessary tools and equipment to carry out high quality hydrographical surveys.

    The specialists within the Survey Department operate hydrographical survey vessels and have developed an advanced data management system to allow precise surveying and early handling and interpretation of the gathered data.

    • General marine project management such as writing of HSE/QA procedures; documentation and auditing of processes, local training to develop local employment to international quality and safety standards, and ultimately to transfer knowledge, managing base stations, warehouses, storage facilities and workshops.

  • Project financing

    Project financing

    A multitude of complex technical challenges in dedicated marine terminals must be overcome.

    A multitude of complex technical challenges in dedicated marine terminals must be overcome. However, another critically important factor is to ensure that the financial engineering for the project is of equal quality. Risk allocation may be shared between public and private sectors. Such approach requires in-depth studies to identify and analyse these risks.

    CTOW has access to expertise in this field. It can assemble the optimal financial package, customized to meet the client’s needs, and then negotiate the package with potential investors and financial institutions.
