Project Aims and Objectives

Aggregates being dredged from increasingly deeper waters. As a result, we need to know if the ROV survey methods tested in shallow waters will work on wrecks in up to 60m of water.
 
Three unexplored wreck sites were chosen to assess ROV methods. The wreckslay in water depths of between 50m and 60m, and had been surveyed with multibeam sonar, sidescan sonar and magnetometer in Round 2, Year One as part of the geophysical section of the current round of the project. The geophysical data from these surveys was used as a basis for the ROV survey.
 
All three sites were subject to an ROV survey aiming at level 2 or 3 recording.
 
This report is divided into two parts. Firstly, a methodological section which discusses the individual deep ROV project objectives. Secondly, the archaeological results of the fieldwork are presented.
 

Project Aim

The aim of the project is to provide industry, regulators and contractors with a framework for the incremental, decision-oriented investigation of wreck sites and with guidance on their archaeological assessment, evaluation and recording.
 
A framework like this is important when considering the cost and time implications marine archaeological investigations.
 
It is also important for developing effective communication between industry, regulators and contractors.
 

Project Objectives

  • Develop and refine methodologies for assessing, evaluating and recording sites in deeper water.
  • Assess the effectiveness of undertaking archaeological recording (to Levels 2 and 3) using ROV and geophysical techniques only.
  • Assess environmental issues (e.g. depth, distance from port, fetch) in respect of working on sites in deeper water.
  • Assess infrastructure issues (e.g. anchoring, tow cable handling, umbilical handling) in respect of working on sites in deeper water.
