Claim 8:
9. A flange connection having a longitudinal centre axis, the flange connection comprising:
a first flange element comprising:
a first attachment part,
a first front side with a first front surface, and
a first flange part, and

a second flange element comprising:
a second attachment part,
a second front side with a second front surface, and
a second flange part,

wherein the first attachment part and the second attachment part are adapted for secure attachment to a tubular element comprising a tower section of a tower structure for a wind turbine or a pipe element that is part of an offshore load bearing structure,
wherein the first flange part and the second flange part are adapted to be arranged radially on an inside of the tower structure or the offshore load bearing structure,
wherein the first flange part is provided with a first flange wedge comprising:
a first flange wedge surface that is part of the first front surface, and
a first flange heel comprising a first flange heel surface that is part of the first front surface,

wherein the first flange wedge surface makes a first wedge surface angle and the first flange heel surface makes a first heel surface angle with a plane that is perpendicular to the longitudinal centre axis of the flange connection,
wherein the second flange part is provided with a second flange wedge comprising:
a second flange wedge surface that is part of the second front surface, and
a second flange heel comprising a second flange heel surface that is part of the second front surface,

wherein the second flange wedge surface makes a second wedge surface angle and the second flange heel surface makes a second heel surface angle with the plane,
wherein the first flange element and the second flange element are adapted to be securely and disconnectably connected to each other, and
wherein the first flange element is provided with a first flange recess that extends around a circumference of the first flange element and separates the first flange wedge and the first flange heel, and the second flange element is provided with a second flange recess that extends around the circumference of the second flange element and separates the second flange wedge and the second flange heel.
