Clamp device and method for repairing a damaged part of a pipe section, and use of such clamp device

A method for repairing a damaged part of a pipe section with a clamp device, wherein the clamp device is adapted to be arranged at said damaged part, the clamp device comprising:

• a patch member,
• a support structure comprising a clamp body supporting the patch member,
• a clamping arrangement, a first engagement member configured to engage with a first part of the pipe section adjacent to the damaged part, and a second engagement member configured to engage with a second part of the pipe section adjacent to the damaged part, which first part and second part of the pipe section are on opposite sides of the damaged part in respect to the pipe section,
• wherein the clamping arrangement comprises a first mechanism, configured in a first step of operation of the clamp device, to engage the first engagement member with the first part of the pipe section and compress the patch member at said damaged part,
• wherein the clamping arrangement further comprises a second mechanism, configured in a second step of operation of the clamp device, to engage the second engagement member with the second part of the pipe section and induce a compressive force between the first engagement member and the second engagement member, and
• wherein the clamp body comprises a first wall portion and a second wall portion defining a recess for the patch member, wherein the first wall portion and the second wall portion are displaceable in respect to each other, wherein the first mechanism is configured to induce a compressive force between the first wall portion and second wall portion, thereby displacing the first wall portion and the second wall portion in respect to each other and compressing the patch member in the recess at said damaged part,
• the method comprising:
• arranging the clamp device on said damaged part of the pipe section so that the patch member is positioned at the damaged part, the first engagement member is positioned at the first part of the pipe section, and the second engagement member is positioned at the second part of the pipe section,
• activating the first mechanism, wherein the first engagement member engages with the first part of the pipe section and the patch member is compressed at said damaged part, and
• activating the second mechanism, wherein the second engagement member engages with the second part of the pipe section and the second engagement member is pushed toward the first engagement member.
