About Us


In 1975 the marine contracting company 'Dickerman Overseas' was established. The focus was to offer the shipping/off shore industry a turnkey contracting service for tank cleaning and coating programmes (but not limited to) whilst the vessel/rig remains in operational service.
As such the Dickerman Group continues to carry out contracting services for clients such as Exxon Mobil, BP, Hess, Shell, Marathon Oil, OSG ship management, MOL tank ships, Dolphin drilling and PRO safe offshore.
Over the years other divisions within the Dickerman Group have been established; Si-Serve, Si-Jet and ADV communications.

Si-SERVE is the UK contracting division of the Dickerman Group. This division of the group carries out various contracts in the water sectors. Contracts range between potable and waste water projects from small scale pressure filters up to large scale contracts working on slow sand filters.

The Si-Serve current client list includes; Thames Water, Bristol Water, South East Water, Affinity Water, Southern Water (BTU) & many more.  All squad members are fully trained to the highest standard including entering confined spaces and dealing with the hazards that they come across in a safe and professional manner.

Si-Jet is a development division which designs and sells venturi effect jet pumps to numerous marine/petrochemical and water industries on a worldwide basis. This pump is utilised throughout the water, shipping, offshore industry & within all of our cleaning based projects - documentation available upon request.
